The primary and secondary filaments are intermingled in a treatment zone 24 by means of turbulent fluid flow, the primary filaments being fed to the zone 24 as one or more multifilament yarns at a rate 4 to 26% higher than that at which the intermingled filaments are withdrawn from the zone, the secondary filaments being fed as one or more yarns 2 at a rate at least 2.5% higher than that of the primary yarn 1 and up to 30% higher than the rate of withdrawal of the intermingled filaments at least one of the yarns being wetted and passed whilst still wet into the treatment zone 24. In the embodiment shown a 167 decitex 72 filament polyester yarn, a 78 decitex 20 filament nylon 66 yarn 2 and a 167 decitex 72 filament polyester yarn 3 are are fed at 336, 345 and 363 m/min respectively by portions 11, 12 and 13 of a stepped feed roll. Secondary yarn 3 is passed through water bath 30 then all three yarns are passed through a turbulent air flow chamber 24. The composite yarn 31 is withdrawn at 300 m/min and passed several times around rollers 35 so that it contacts 220‹C contact heater 33 and is relaxed and shrunk circa 10%. The yarn is withdrawn from the heater at 255 m/min and wound up on mandrel 34 at 270 m/min. The heater may be enclosed. Bulking of a second yarn using the same apparatus is described.

Title: Improvements in or relating to rotary piston compressor
IPC: F04C29/02
Filed: 1970-11-19
Abstract: 1293080 Rotary pumps KUHLAUTOMAT VEB 19 Nov 1970 55133/70 Heading F1F In a rotary piston compressor of the intermeshed screw type, having a suction inlet 6 in one end-wall and a pressure outlet in the other, 5, and in which oil, for lubricating, cooling and counteracting axial thrust, is pumped to the endwalls, where it is collected and thence directed into the circuit of the operating medium, which latter is soluble in oil, the pressure energy in the oil or foamed mixture, in relation to suction pressure, is used for injecting it at the maximum possible speed into the suction chamber 6, through one or more nozzles 10, orientated towards the auxiliary rotor 3 in the direction in which the operating medium enters a tooth gap.  In contrast with existing arrangements in which the high-pressure foamed liquid is introduced directly through cavities to the low-pressure end of the compressor, this avoids the loss of compressor delivery volume due to evaporation of the operating medium from the oil at the lowpressure end, and the subsequent dissolving of operating medium in the oil as it passes through the compressor. Further the pressure wave produced by the high entry speed of the foamed oil may result in pre-compression of the operating medium. The return oil passages 8, 9 from the high and low-pressure end-walls may lead to separate nozzles, parallel in Fig.2 (not shown) and concentric in Fig.3, (not shown), the outer nozzle receiving the high-pressure 8 and producing an ejector action on the inner nozzle which receives the low-pressure 9. A single nozzle such as 10, Fig.1, or two such concentric nozzles may discharge through a third concentric nozzle, Figs.4 and 5 (not shown) for further ejector action.
